Snake River Prototyping V+ Series ND4/CP Filter for DJI Phantom 2 Vision Plus Camera V+ Series ND4/CP Filter Storage case Microfiber cleaning patch The V+ Series ND4/CP Filter combines a lightweight slip-over filter frame for the DJI Phantom 2 Vision+ camera with a professional grade two-in-one filter. The ND4/CP is a combination circular polarizer and neutral density 4 (ND4 or ND0.6) filter. A CP filter is used to reduce glare on the surface of water or windows, manage reflections, and increase the contrast between clouds and sky. A neutral density filter is used to reduce the effects of rolling shutter including the jello effect and prop blur. Filter weight is only 7.2 g, or 0.25 oz! Each V+ Series Filter is made from two CNC machined Delrin pieces so that the filter frame can be disassembled to facilitate easy cleaning of the filter glass. Delrin, which is more costly than billet aluminum by volume, was selected because of its high quality and excellent machining qualities.
